Flo-tech”s PFM6 portable hydraulic testers are designed for fast diagnostic troubleshooting of all types of mobile or stationary hydraulic systems and components. The testers, which provide laboratory accuracy, are compact, durable, and self-contained. The test unit provides full-range accuracy of +/- 1 percent with a turbine flow sensor for fast response. It features a large 3.5-digit LCD for both flow and temperature, a platinum-resistance thermometer, and a swept wet well. A one-toggle switch controls power, flow, and temperature. The load valve offers fingertip control of pressure to 6000 PSI/414 Bar. Another Flo-tech model, the PFM6BD, has the same features as the PFM6, but provides in-line testing of servo systems, valves, and bi-directional motors. The PFM8 tester and dynamometer has a front panel for U.S. or metric readings and a large membrane switch that selects flow, temperature, pressure, and power. It reads digital pressure to 6000 PSI/414 Bar, and the dynamometer reads HP and kW directly. The low noise input circuitry provides steadier readings when flow is pulsating or cavitating. An auto/off automatically turns power off after five minutes with no flow signal. This model also has the same features as the PFM6.
